Professor Richard Lindzen of MIT is one of the world’s greatest atmospheric physicists. He spoke to the House of Commons this last week. As James Delingpole says:

“Dick Lindzen does not need to raise his voice. He does not use hyperbole. In a tone somewhere between weariness and withering disdain, he lets the facts speak for themselves. And the facts, as he understands them, are devastating.

Here is how he began his speech, which was organized on behalf of the Campaign to Repeal the Climate Change Act:”

Stated briefly, I will simply try to clarify what the debate over climate change is really about. It most certainly is not about whether climate is changing: it always is. It is not about whether CO2 is increasing: it clearly is. It is not about whether the increase in CO2, by itself, will lead to some warming: it should. The debate is simply over the matter of how much warming the increase in CO2 can lead to, and the connection of such warming to the innumerable claimed catastrophes. The evidence is that the increase in CO2 will lead to very little warming, and that the connection of this minimal warming (or even significant warming) to the purported catastrophes is also minimal. The arguments on which the catastrophic claims are made are extremely weak – and commonly acknowledged as such. They are sometimes overtly dishonest.
